In its 20-year history, the SIU has conducted at least 3,400 investigations and laid criminal charges after only 95 of them, according to a Star analysis. The SIU does not track what happens to those it charges. But the Star has, and found only 16 officers have been convicted of a crime
3400/20 = 170 investigations per yr
95/20 = 4.75 charged per year
16/20 = 0.8 per year found guilty of the alledge offence
And this is news how??
Same as any other investigation, if there is no evidence to support the charge, you can not just lay a charge. Further, as every citizen police still have their right to a trial and then a judge determines the outcome.
